As oil and gas exploration and production moves into deeper reservoirs and more
challenging environments, higher temperatures, higher pressures and more corrosive
environments make corrosion place increased demands on inhibitor availability, with
designs based on over 99% availability becoming increasingly common. Maximizing
corrosion inhibitor performance is key to reducing risk, preventing failures, extending life
and deferring replacement costs.
The corrosion inhibitor availability model is commonly used as a measure of the
effectiveness and potential viability of inhibition. Recent work has revisited the corrosion
inhibitor availability concept and the underlying principles to develop an integrated system
approach to maximizing corrosion inhibitor performance. This paper presents a system
approach to delivering high levels of corrosion inhibitor performance based on the
component parts that make up inhibitor efficiency and availability.
